SPECIFICATION forming part Of Letters Patent N 0. 662,989, dated.December 4, 1900.

Application filed January 29, 1900. erial No. 3,204. (No model.)

useful Improvements in Valves, of which the following is aspecification, reference being had therein to the accompanying drawings.

My invention relates to valves, and more especially to those designedfor use in connection with flushing-tanks.

The invention consists in the construction whereby the valve is guidedand seen red from accidental displacement in relation to its seat;further, in the means employed for weighting said valve, and, further,in the peculiar construction, arrangement, and combination of parts, asmore fully hereinafter shown and described.

In the drawings, Figure 1 is a perspective view. Fig. 2 is a verticalcentral section thereof, and Fig. 3 is a bottom plan illustrating one ofthe locking-catches.

A is the fitting upon which the seat is formed and which may be of anysuitable construction.

B is the valve. This, as shown, is of the disk form and is preferablyprovided with a central lug or ear C, to which the valve-rod D isattached. The lowerface of the disk is provided with suitable packing,such as E, which may be secured in any suitable way, as by the screw Fand washer G.

Upon opposite sides of the valve are arranged two downwardly-projectingarms or guides H, which are adapted to embrace the seat-fitting A, andthe latter is provided with grooved bearings to receive said guides,preferably formed by the ears or lugs I, arranged upon opposite sides ofthe arm H and forming between a channel in which said arm slidinglyengages. At the lower ends of the arms H are arranged suitable catchesadapted in one position to engage with the lugs I and prevent thedisengagement of the arms H from their channels. These catches I haveshown as comprising a U-shaped loop J and which is engaged with the armH by providing the latter with the bifurcated projection K, one of theprongs of which may be turned over said wire loop to hold the same inposition, as shown in Fig. 1. The catch thus formed when turned with itsswinging arms a in a vertical position will'allow the arms H to beengaged or disengaged with their guide-channels on the seat-fitting; butwhen said latch is turned in a horizontal position its arms will engagewith the lugs I and prevent the disengagement of the arms H. To hold thecatch from turning beyond its horizontal position, a lug or shoulder Lis formed on the arm H below the catch, upon which the arm at of saidcatch is adapted to rest.

As the valve B is moved to its seat by its own gravity it is necessarythat it should be suitably weighted. To accomplish this in a simplemanner, I recess the upper face of the disk around the central ear 0 andinto the cup thus formed cast a soft metal M of greater specificgravity, such as lead. This not only weights the valve, but the lead isalso securely attached thereto.

It is obvious that in place of forming the arms H upon the valve B, Imay place them upon the fitting A and the lugs I upon the valve B. Ibelieve, however, that the arrangement shown is the preferable one.

A valve thus constructed may be readily attached or detached from itsseat-fitting by the simple operation of turning the catches J, and whensaid catches are in their locking positions the valve is securely heldfrom disengagement.

What I claim as my invention is- 1. The combination with a valve and theseat-fitting therefor, of guide-arms on the one embracing the other,guide lugs or shoulders on the latter for guiding said arms and movablecatches attached at the end of said arms adapted in one position toprevent the disengagement of said arms from said lugs and in anotherposition to permit said arms to pass freely between said guide-lugs.

2. The combination with a valve and the seat-fitting therefor, of aguide-arm on the one engaging a channel in the other, and a catchpivoted to the side of said arm adapted when turned in one position topermit of the engagement or disengagement of said arm taining said loopand a lug or stop for said I0 loop in its locking position. a,

In testimony whereof I affix my signature in presence of two Witnesses.

WILLIAM TAYLOR.
